Notes:
Common in gardens, parks, woodland, heathland and moorland throughout the British Isles; well distributed across much of Hampshire and on the Isle of Wight. Wingspan 30-35 mm. Unmistakable resting posture with forewing folded in on itself at the costa only shared by the much larger Angle Shades Phlogophora meticulosa. The larva is one of the few to feed on bracken and other ferns, but will also feed on a variety of herbaceous plants and shrubs, including birch and sallow, over-wintering as a pupa.
